Answer:
Step-by-step explanation:
First, find the slope of the given line by finding two points. (0, 3) and (1, 1)
Use the equation for slope rise/run to find the slope.
From the left point to the right point, it goes down 2 units and to the right by 1 unit
-2/1 = -2 = slope
We already know the y-intercept which is y = 3, when x=0 and when the line crosses the y-axis
y=-2x+3 is the equation of the line.
Perpendicular line's slope is the opposite reciprocal of the original line's slope. Opposite reciprocal of -2 would be 1/2
y = 1/2(x)
y=1/2x -5/2
Answer:
yes they are congruent because they have the same size and shape
Step-by-step explanation:
Answer:
- a) f(x) = - 20x + 450
- b) 30 pages left to read
Step-by-step explanation:
<u>Given sequence:</u>
The first term is 430 and the common difference is - 20.
a)
<u>Required function is:</u>
- f(x) = 430 - 20Ix - 1) = 430 - 20x + 20 = 450 - 20x
or
b)
<u>Find the number of pages left after 21 days:</u>
- f(21) = 450 - 20*21 = 450 - 420 = 30
solve for k by simplifying then isolating the variable ... K equals 0
